[Sofia-sip-devel] NOTIFY sip frag set to 503 when receiving 407 Invite response

[Nauman Sulaiman]

Hi, when performing an attended transfer, when the transfer destination sends a 
407 to the INVITE with replaces generated by transferee, a NOTIFY with 503 
sipfrag is sent to the transferrer. Code is here in nua_session.c
in function nh_referral_respond. The transfer destination is in different
domain. The resulting NOTIFY 503 sent to the transferrer makes him think the 
transfer has failed rather than just being in progress. Is there some reason 
for this or is it a bug?


if (status = 300)
status = 503, phrase = sip_503_Service_unavailable;

  snprintf(payload, sizeof(payload), SIP/2.0 %03u %s\r\n, status, phrase);

  if (status  200)
substate = active;
  else
substate = terminated ;reason=noresource;

  nua_stack_post_signal(ref-ref_handle,
nua_r_notify,
SIPTAG_EVENT(ref-ref_event),
SIPTAG_SUBSCRIPTION_STATE_STR(substate),
SIPTAG_CONTENT_TYPE_STR(message/sipfrag),
SIPTAG_PAYLOAD_STR(payload),
TAG_END());

 
Regards

I think it is a bug, the stack should check if the request is restartable.
